Work your biceps, shoulder, triceps, and upper back without disrupting your centre, Parrish says.
Come standing tall with your feet hip-width apart. Draw your navel into your spine and up into your ribcage.
Squeeze your shoulder blades together on your back as you pull your front lower ribs together — this is your powerhouse. Don't let it go until you have finished this whole series.
With your arms at your sides, bend them to make 90-degree angles with your elbows slightly behind you and your palms facing up.
Inhale, without losing your powerhouse, extend your arms forward like you were passing a tray to someone directly in front of you.
Reach the energy through your fingertips as you draw your ribs back. And don't let your hands and arms go higher than shoulder height.
Exhale, use your back and the back of your shoulders to draw your elbows back into your waist.
